Abstract
BACKGROUND: There are several studies which evaluated the number of infections caused by enteric pathogens, including Clostridioides difficile in patients with inflammatory bowel disease (IBD). Our aim was to assess the prevalence of intestinal infections among patients suffering from IBD, when admitted to the hospital due to exacerbation of the disease. RESULTS: The performed, retrospective analysis covered test results for C. difficile toxins A and B along with rectal swab cultures sampled from patients, treated in a tertiary IBD center in Poland, between 2017 and 2019. Main objective was to estimate the presence of any infection, which could imitate or co-exist along with the exacerbation of the IBD. All in all 1471 patients had microbiological tests performed, including 1112 tested for C. difficile toxins A and B; and 359 patients who had rectal swab culture. Positive test results for C. difficile toxins A and B were reported in 358 cases, positive results from rectal swab culture were confirmed altogether in case of 25 samples. As far as patients with IBD are concerned, positive results for C. difficile toxins A and B were detected in 82 cases, positive results in rectal swab culture from patients with IBD were reported in 20 cases. CONCLUSION: Intestinal infections were reported in 14.9% of patients (102/685) with IBD symptoms. Positive test results for C. difficile toxins A and B and rectal swab cultures among patients without IBD symptoms were reported in 35.7% of cases (281/786). Intestinal superinfections may complicate the clinical picture of IBD patients, increasing the diagnostic and therapeutic burden. Appropriate early procedures are thus needed in these patients.
